The KTM 505 SX has a lot to love. It features a strong personality, a powerful engine and is also reliable to the core. All these features make one of the most capable ATVs in its class.
At the heart of the ATV lies a powerful, liquid-cooled four-stroke, single-cylinder engine, which offers a wide usable rev range, and is paired with a close-ratio, five-speed transmission. The engine is kept in check by a hydraulic clutch and breaths through a 34 mm Keihin carburettor. The four stroke unit is brought to life by a small lightweight electric which does a brilliant job at any time.
If you want to bring the KTM 505 SX to halt, the four-piston fixed-caliper brakes from Magura and two wave discs are there to serve you.
As far as suspensions are concerned, the front axle is fitted with independent wheels suspension with double wishbone while out back there is a rigid axle.
